The synthesis and reactions of the first moisture-insensitive triarylbismuthane imide (7), bearing an oxazoline ring at a position ortho to the carbon bearing the bismuth atom, are described. The firstX-ray crystallographic study of bismuthane imide has been carried out for compound 7, which revealed that the bismuth center possesses a distorted-trigonal-bipyramidal geometry and the Bi−N(imide) bond

bromide 16b coalesced in pyridine-d5, 1,2-dichlorobenzene-d4, chlorobenzene-d5, and toluene-d8. The coalescence temperature (Tc) depended on the nucleophilicity of the counteranions as well as on the polarity of the solvents; Tc decreased as the nucleophilicity of the counteranions increased or as the polarity of the solvent decreased. Thus, the configuration at bismuth in tetrafluoroborates 14 and tosylate
